The watch looks lovely, but a bit bulkier than looks online. I am using with an IPhone, it does say that it is IOS compatible, but a lot of the features aren’t available. It isn’t made at all clear that you can’t use 4G on an iPhone with the Watch, so you need to carry your phone with you at all times. No email, no Facebook and notifications are a bit hit and miss. May consider getting a galaxy phone. Great for all the fitness stuff though.
